ELSTIC VEHICLE-WHEEL.

Specification of Letters Patent.

Patented April 24, 1906.

Application led August 17, 1904. Serial No. 221,074.

To 1r/ZZ whmrb it may concern.-

Be it known that I, FRANK L, HARMON, a resident of Beverly, in thecounty of Essex and Commonwealth of Massachusetts, have invented anElastic Vehicle-Wheel, of which this is a specification, reference beinghad to the accompanying drawings.

The object of my invention is to provide an elastic vehicle-wheel whichon account of its elasticity may not impart much jar to the body of thevehicle and may not be liable to puncture a tire, and in order to dothis I provide an elastic vehicle-wheel having spokes` which are springsimmovably secured at the wheelerim and between said rim and the centerof the wheel and extending out of a direct line from the center of thewheel to its rim, said wheel also having means whereby the wheel may bestil'ened located between the points where the spokes are immovably secufed.

In the accompanying drawings numerals are used to designate the parts.

Figure 1 is a side Velevation of this new wheel; and Fig. 2 is avertical section of it on line 2, indicated by the arrow near Fig. 1.Fig. 3 is a perspective detail of means whereupon the wheel may beproperly stiffened.

The rim 2 (shown as wood) maybe of metal and is provided with a hollowor pneumatic tire 1. To the rim 2 the yielding spokes 3 are secured bythe bolts 4 and also to the hub 10 by the screws 5. The spokes it in agroove .sired load and yiel shown in the eriphery of said hub, as shownin Fig. 2. T 1e long bearings of said spokes on the rim 2 are to supportthe rim. The

ring 6 shown in Fig. 3 is shown secured to the hub 10 in Figs. 1 and 2by the screws 7, threaded in said hub and extending through the slots 11in said ring, and the studs 8 are shown in the V-shaped openings shownbetween said spokes and said hub in Fig. 1.' Before the screws 7 aretightened a crow bar may be inserted between thestuds 9, (shown fast insaid ring 6,) and the ring may be thereby turned on the hub, so as toforce all the studs against all the spokes in order to stiften thewheel, so as to roperly sustainthe ded properly/and prevent puncturingthe tire when it violently strikes an obstacle.

Having thus shown and described my inventionj claim An elasticvehicle-wheel comprising spokes which are springs, one end of each spokebeing immovably secured at the rim or circular part of the wheel, andthe other end of each spoke being immovably secured between the rim orcircular part and the center of the wheel, said spokes extending in anindirect line from the center of the wheel to said rim or circular part,and said s okes being adapted to spring in the direction that the wheelgoes, and adjustable means whereby the wheel may be stifiened locatedbetween the points where said spokes are thus immovably secured.
